In a shock nighttime newsbreak, Indianapolis quarterback Andrew Luck is retiring from the NFL.

The news was first reported by ESPN's Adam Schefter. Luck is only 29 years old, and has dealt with several injuries over the past few years.

An emotional Luck said in the press conference that he has been stuck in a "pain cycle" over the previous four years. He also added that he originally expected to tell his teammates of his retirement on Sunday.

A further twist to the sudden news: it broke in the middle of the Colts' preseason matchup against the Bears.

WTHR Reporter Rich Nye posted a video to his Twitter page from the stadium of fans booing Luck as he left the field when the news broke. When asked how Luck felt during the press conference, he said that it hurt.

However he also said during the press conference that the decision to walk away was the hardest decision of his life and expressed tremendous amounts of love for the fans and the organization.

Andrew Luck was drafted in 2012 first overall out of Stanford. He was one of the NFL's top performing quarterbacks up until 2017 surgery on a torn labrum in his shoulder and the recovery setbacks that followed forced him to miss significant time.

Backup quarterback Jacoby Brissett is next in line on the Colts' depth chart.
